Northern white lipped python for sale

I am reluctantly selling my northern white lipped python. He is a CB19 male with breeders certificate.
He is healthy, just had a full shed and a veracious appetite. Currently feeds on medium rats.
Is housed presently in a 5ft long, 3ft tall and 2ft deep plastic vivarium with a deep heat projector and uv forest T5 tube. He would however benefit from a larger enclosure now as he is about 6ft long approx and uses all of his space. He also likes to climb so needs a bit of height.
To note this is not a beginner snake and does have a fiery temperament and is quite cage defensive.
He is however a an active snake, particularly at night, but will often come out in the day when he wants food and displays beautiful iridescent colours under the UV and LED lights of the enclosure. The enclosure is for sale at an additional cost of £200. Proof of a suitable enclosure will be required on sale if not purchasing his current one, and I may ask questions around experience also to ensure he is going to a suitable keeper.
Only selling due to house move and other circumstances.
